Abstract: A machine (2) is adapted for operation powered by any one of a plurality of interchangeable power sources (33). The machine (2) may include an undercarriage configured for supporting ground engagement members (4) that propel the machine (2) and an upper structure (6) rotatably supported on the undercarriage. The upper structure (6) may include a swing frame (22), with the swing frame (22) supporting an operator cab (24), any one of the plurality of interchangeable power sources, hydraulic components, electrical components, and a counterweight (126, 226) disposed at a first end of the swing frame. The counterweight (226) may include a hollowed out portion (222) facing toward the swing frame (22). The hollowed out portion (222) of the counterweight (226) may be centrally aligned with a center core portion (310) of the swing frame (22) configured for supporting any one of the plurality of interchangeable power sources (33), with the one power source being partially accommodated within the hollowed out portion (222) of the counterweight (226).

Abstract: Provided is a hood device that can reliably fix a plurality of hood members to an upper side of a machine room without using a beam member arranged on the upper side of an engine. One hood member (21), which is fixed to an upper side opening edge (23) of a machine room (15) in a closed state, is disposed at a part of an upper side opening of the machine room (15) so as to open and close. The other hood member (22), which is fixed to the upper side opening edge (23) of the machine room (15) in a closed state, is disposed at other part of the upper side opening of the machine room (15) adjacent to one hood member (21) so as to open and close. One hood member (21) includes: a reinforcing deformation part (49) which is disposed along one notch-like edge portion (24) positioned above a part adjacent to the other hood member (22) and has a protruded-shape cross section upward; and a pressing portion (53) which is disposed at one notch-like edge portion (24) along the reinforcing deformation part (49) and protrudes downward. The other hood portion (22) includes a pressed groove portion (58) which is disposed at a place corresponding to the pressing portion (53) of one hood member (21) and has a recessed-shape cross section upward.
